In reading this morning I came across the results of some experimenting being done at MIT that really captured my attention. In short, using nano technology they have demonstrated in lab tests (not commercially available yet) that a solar collector can be designed to capture solar energy and then store that energy as heat until that energy can be used "on demand" to then produce electricity.Tthe implications here are quite exciting. Here's a link to some of that information http://www.gizmag.com/solar-power-nanoscale-thermophotovoltaic-system/30528/?utm_source=Gizmag+Subscribers&utm_campaign=f4566917a2-UA-2235360-4&utm_medium=email&utm_term=0_65b67362bd-f4566917a2-90360106
